Whites detectors are the best on the market. You can pay more for a MnLb but for much less money you own a detector that will get the job done and by a company that stands behind every product they sell. I have done air tests with .1 gram gold and it signals at 12". Bigger nuggets scream. The build quality is next to none. All of the connections are perfectly fitted, the battery pack is easy to service, the headphone jack is top quality as are the control pots. This is a machine that Americans can be proud to use and show because it is built in the "Good Ol' USA". Thanks Whites for being part of the American Dream!
